| Summary: | The Internet has become the point of convergence for data, voice, audio and video.
It is fast becoming the preferred platform for communication and content delivery,
eventually leading to the demise of conventional PSTN telephone network and terrestrial/
satellite television. Video streaming is experiencing an unprecedented growth
it currently accounts for more than half the Internet traffic and is expected to reach
82% in the next 3 years. The transmission of video and other time-sensitive content
uses UDP (as opposed to TCP) because this protocol improves quality of service
(QoS) in terms of providing fast and efficient transmission. Various types of QoS architecture
have been proposed and deployed to further improve the quality of video
transmission for example, integrated service, differentiated service and multiprotocol
label switching. Recently, software-defined networking (SDN), a network virtualisation
architecture, has introduced the possibility of further improving QoS, especially
for multidescription coded video streaming. In the current design, such videos are
transmitted over a single path that can lead to deteriorated QoS. Owing to the nature of
multiple description coding (MDC) videos, the descriptions of the video can be separated
and sent over multiple paths by taking advantage of the SDN design and features.
Existing methods do not consider the best use of error-resiliency when deciding the
multipath. |
